It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-68243 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-68243/ (Markdown: https://insights.sbomify.com/CVE-2025-68243/index.md)","id":"CVE-2025-68243","markdown":"https://insights.sbomify.com/CVE-2025-68243/index.md","name":"CVE-2025-68243","record":{"aliases":["BELL-CVE-2025-68243","DEBIAN-CVE-2025-68243","GHSA-3m9h-22j9-8m85","UBUNTU-CVE-2025-68243"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel NFS","requires_auth":"low_privilege","summary":"Attackers can bypass NFS TLS client identity verification by exploiting missing certificate field checks in the Linux kernel.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nNFS: Check the TLS certificate fields in nfs_match_client()\n\nIf the TLS security policy is of type RPC_XPRTSEC_TLS_X509, then the\ncert_serial and privkey_serial fields need to match as well since they\ndefine the client's identity, as presented to the server.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"NFS: Check the TLS certificate fields in nfs_match_client()","id":"CVE-2025-68243","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"drm/i915: Avoid lock inversion when pinning to GGTT on CHV/BXT+VTD","id":"CVE-2025-68244"},"packages":[],"prev":{"headline":"NFS: Fix LTP test failures when timestamps are delegated","id":"CVE-2025-68242"},"products":["Linux"],"published":"2025-12-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"Attackers can bypass NFS TLS client identity verification by exploiting missing certificate field checks in the Linux kernel.","url":"https://insights.sbomify.com/CVE-2025-68243/"}
